Synthetic predicted light curves of SSN 7 for an inclination angle of i = 16° and the orbital configuration of the binary components in the plane of sky at different phases. Upper panel: Phased synthetic light curve in the Johnson V band. Lower panel: Orbital configuration of the binary components at phases ϕ = −0.5, −0.25, 0.0, 0.25, and 0.5. The models are colour-coded by effective temperature, taking into account the physical effect mentioned in the text.
